The variation of the relative deviation index ϑ(θ) (processed data). The standard errors of estimates acquired by nonlinear regression from processed data, produced θ ste =3.954 × 10− 3). This set a range 0 ≤ ϑ(θ) ≤ 0.003. Thus, the largest absolute deviation between w m (α q , β r ,t) and w m (t) amounts to about 0.3% of the 〈w m (t) 〉 average. Data quality control could be a factor improving accuracy of w m (α,β,t) projections
